After upgrading to app-shells/bash-3.2 my laptop stopped booting. At the start
of sysvinit the system tells me that the kernel is missing support for tmpfs,
which it does not.
Downgrading to app-shells/bash-3.1_p17 solved the issue.

In bash 3.2 the binary operator =~ is broken.
[[ "one two three" =~ "one (.*) three" ]] && echo $? ${BASH_REMATCH[1]} || echo
$?
bash 3.1_p17 gives 0 two
bash 3,2 gives 1
The exact call in baselayout that is failing is this
local filesystems=$(</proc/filesystems)
if [[ ${filesystems} =~ "[[:space:]]tmpfs"$'\n' ]] ; then
fs="tmpfs"
else
<work out ramfs, etc>
fi
baelayout-1.12 shouldn't be affected by this as we use these tests in 1.13
(currently alpha, unstable and p.masked)
3.2 Changelog
f. Quoting the string argument to the [[ command's =~ operator now forces
string matching, as with the other pattern-matching operators.
match="one (.*) three"
[[ "one two three" =~ ${match} ]] && echo $? ${BASH_REMATCH[1]} || echo $?
now gives
0 two
in bash 3.2
That sucks
I suppose we could do
match="one (.*) three"
[[ "one two three" =~ ${dummyvar:-one (.*) three} ]] && echo $?
${BASH_REMATCH[1]} || echo $?
which works also, but that sucks too.
Hmmmmmm
I have another problem with bash and baselayout,
related with reboot and poweroff,
after their run
/sbin/reboot or /sbin/poweroff
I got something
INIT: no more processes left on runlevel
and root filesystem not unmounted correctly, and machine was not rebooted, or
halted, I have to do it manualy,
downgrade to < bash-3.2 was solved the problem.
baselayout 1.12.5-r2
bash 3.2
Although this bug is only about =~ semantics, I'd like to note (just not to
forgive about this) that there are some other problems with bash-3.2. Fex,
compilation of kate and some other packages became broken. And I have not
checked but may be this error also exist:
http://lists.gnu.org/archive/html/bug-bash/2006-10/msg00046.html
the KDE issue is tracked in another bug ... it's a different issue so it gets a
different bug
baselayout-1.12.6 works with all bash versions.
