[--interactive] Non-bash shells and busybox

[eine]

Related to #87.

The following dockerfile:

FROM alpine
RUN apk update && apk add xterm

docker build -t alpine_term .

works as expected if a GUI app is executed directly:

x11docker alpine_term xterm

However, when -i is used, some errors are shown:

# ./x11docker -i alpine_term sh
x11docker note: Using X server option --vcxsrv

x11docker note: Per default x11docker stores its cache files on drive C:.
  docker setup may not allow to share files from drive C:.
  If startup fails with an 'access denied' error,
  please either allow access to drive C: or specify a custom folder for cache
  storage with option '--cachebasedir D:/some/cache/folder'.
  Same issue can occur with option '--home'.
  Use option '--homebasedir D:/some/home/folder' in that case.

x11docker note: Did not find container init system 'tini'.
  This is a bug in your distributions docker package.
  Normally, docker provides init system tini as '/usr/bin/docker-init'.

  x11docker uses tini for clean process handling and fast container shutdown.
  To provide tini yourself, please download tini-static:
    https://github.com/krallin/tini/releases/download/v0.18.0/tini-static
  Store it in one of:
    /home/eine/.local/share/x11docker/
    /usr/local/share/x11docker/

BusyBox v1.28.4 (2018-12-06 15:13:21 UTC) multi-call binary.

Usage: find [-HL] [PATH]... [OPTIONS] [ACTIONS]

Search for files and perform actions on them.
First failed action stops processing of current file.
Defaults: PATH is current directory, action is '-print'

        -L,-follow      Follow symlinks
        -H              ...on command line only
        -xdev           Don't descend directories on other filesystems
        -maxdepth N     Descend at most N levels. -maxdepth 0 applies
                        actions to command line arguments only
        -mindepth N     Don't act on first N levels
        -depth          Act on directory *after* traversing it

Actions:
        ( ACTIONS )     Group actions for -o / -a
        ! ACT           Invert ACT's success/failure
        ACT1 [-a] ACT2  If ACT1 fails, stop, else do ACT2
        ACT1 -o ACT2    If ACT1 succeeds, stop, else do ACT2
                        Note: -a has higher priority than -o
        -name PATTERN   Match file name (w/o directory name) to PATTERN
        -iname PATTERN  Case insensitive -name
        -path PATTERN   Match path to PATTERN
        -ipath PATTERN  Case insensitive -path
        -regex PATTERN  Match path to regex PATTERN
        -type X         File type is X (one of: f,d,l,b,c,...)
        -perm MASK      At least one mask bit (+MASK), all bits (-MASK),
                        or exactly MASK bits are set in file's mode
        -mtime DAYS     mtime is greater than (+N), less than (-N),
                        or exactly N days in the past
        -mmin MINS      mtime is greater than (+N), less than (-N),
                        or exactly N minutes in the past
        -newer FILE     mtime is more recent than FILE's
        -inum N         File has inode number N
        -user NAME/ID   File is owned by given user
        -group NAME/ID  File is owned by given group
        -size N[bck]    File size is N (c:bytes,k:kbytes,b:512 bytes(def.))
                        +/-N: file size is bigger/smaller than N
        -links N        Number of links is greater than (+N), less than (-N),
                        or exactly N
        -prune          If current file is directory, don't descend into it
If none of the following actions is specified, -print is assumed
        -print          Print file name
        -print0         Print file name, NUL terminated
        -exec CMD ARG ; Run CMD with all instances of {} replaced by
                        file name. Fails if CMD exits with nonzero
        -exec CMD ARG + Run CMD with {} replaced by list of file names
        -delete         Delete current file/directory. Turns on -depth option
cp: can't stat '/etc/skel/.': No such file or directory
~ $

This log is from Win10. But I get the same result on Arch Linux.

I think this is because the implementation of some tools in alpine (https://busybox.net/) is not exactly the same as those in common distributions.

I could reproduce, it's fixed now. Thanks!
