Summary: Post-install scripts executed twice
Initial Comment:
Setup: server running debian etch, systemimager 3.7.6
Image name: sargetest
Hostname: tests1
Script: 90sargetest.script (in /var/lib/systemimager/scripts/post-install)
Post-install scripts with a class name are executed twice in my setup (scripts
with "all" class are not concerned).
This bug is actually in the functions file (/etc/init.d/functions in initrd.img
and in intrd template), in function run_post_install_scripts.
I just fixed this using sort -u instead of uniq, and it looks something like :
POST_INSTALL_SCRIPTS=`sort -u << EOL
$POST_INSTALL_SCRIPTS
EOL`
And it works just fine now. You may find a smarter way to fix this, just my 2
cents ;)

The command uniq (as sort -u) works only if the list is sorted, but we
want to preserve the order of the different classes (IMAGENAME,
BASE_HOSTNAME, HOSTNAME, all, OVERRIDES), so we cannot sort the whole
list with a single command.
The solution is to use a custom unique() function to remove duplicate
entries preseriving the original order.
unique() {
ret=
for i in $*; do
flag=0
for j in $ret; do
[ "$i" = "$j" ] && flag=1 && break
done
[ $flag -eq 0 ] && ret="$ret $i"
done
echo $ret
unset i j flag ret
}
Usage:
for script in `unique POST_INSTALL_SCRIPTS`; do
execute script ...
done
Maybe there's a more elegant way to resolve, but this solution seems to
resolve. The fix is present in the trunk and it'll be available in 3.7.7.
Thanks for reporting,
-Andrea
