These issues are not a result of ash being broken, but are because bash has added features that are not available in ash. The string manipulation above is an example of bash-specific script.

If you do a man on ash and go to 'Parameter Expansion' section, these formats are meant to be supported. But they doing work.

Hm, interesting - my next guess is that the included ash binary is not the same version as the manpage you are looking at, or its not compiled in, etc. (since I haven't seen any startup scripts using it, I wouldn't be surprised).

Guess another alternative is to replace ash with one that works to how you want it to.

Another thing, can you log the boot processes? Anyways, did you try running a dummy script inside an ash terminal?

Ah yes.. the 'bash-isms'

If you really don't care about about speed and efficiency I suppose you could try to use bash instead.

Otherwise, I'd suggest for you to replace whatever scripting you're doing with replacement commands or use another implementation. If you decide to go this way, you could paste out your script (or snippets of) to show what you're trying to do with the code and we can try to help.

I am trying to use bash because ash is so limited.

Here is my added code:

NOCD="yes";
# NFS_SERVER="${CMDLINE##*nfs=}";
# NFS_SERVER="${NFS_SERVER%%[ ]*}";
echo NFS_Server="${NFS_SERVER}";
mount -t nfs 10.1.1.12:/tftpboot/DSL /KNOPPIX
set +x; ;; esac
