Bug 284221 – /lib/udev/move_tmp_persistent_rules.sh from sys-fs/udev needs /bin/bash, not /bin/sh

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Raffaello D. Di Napoli 2009-09-08 22:30:46 UTC]

I installed app-shells/dash as a replacement for bash in scripts (mostly for memory footprint); as a part of the process, I also replaced the /bin/sh symlink to one pointing to /bin/dash.

I assumed most of Gentoo has been checked for undeclared dependencies on bash; while I was right, I did find two scripts which use bash but declare /bin/sh instead.
One I already filed a bug for, the other I found out to be /lib/udev/move_tmp_persistent_rules.sh, installed by sys-fs/udev.

I believe this dependency should be made explicit.

Reproducible: Always

Steps to Reproduce:
1. emerge app-shells/dash
2. ln -fs dash /bin/sh
3. reboot
Actual Results:  
(other init messages)
/etc/init.d/functions.sh: 7: source: not found
/etc/init.d/functions.sh: 10: declare: not found
...
(more errors from sourcing functions.sh into a non-bash script)

Expected Results:  
udev-postmount is run, without error messages (it normally displays no output).

Changes #!/bin/sh to #!/bin/bash

move_tmp_persistent_rules.sh sources /etc/init.d/functions.sh (for ebegin and eend), which is entirely bash-dependent, so there’s little to do about it but make explicit its dependency on bash.

[Comment 2 Matthias Schwarzott 2009-09-09 07:11:06 UTC]

My version of /lib/udev/move_tmp_persistent_rules.sh does ". /etc/init.d/functions.sh" and this works without problems:

# dash /lib/udev/move_tmp_persistent_rules.sh

So I think your problem is, you try using dash as system shell, but still use baselayout-1. This combination is NOT supported.
Update to baselayout-2 with openrc and it will work.

Aha, I see.
I now switched to OpenRC and baselayout-2, and yes, it does work for me too.
Thank you all for the assistance.
