The problem breaks down to some lines of code in debian/config.in (I
didn't check it by running, but just by reading the code).
# first we collect those ls-R files which are group writeable in gwritetrue
# and those which are not group writeable in gwritefalse
# furthermore we save the respective group and write permission in
# ${i}group
>
Some informatins are collected here.
# now we save the list of group writeable ls-R files to tex-common/managedlsr
db_set tex-common/managedlsr $gwritetrue || true
#
# and ask the user to check if this selection is ok
db_input low tex-common/managedlsr || true
db_go
#
# get the answer of the users, ie what files should really be group writeable
db_get tex-common/managedlsr && SELECTED_LSR="$RET" || true
if [ -n "$SELECTED_LSR" ]; then
#
# we check wether all the group writeable files belong to the same group
# if yes, we suggest this group and ask the groupname question,
# otherwise we ignore this and do *not* play around with groups.
iscommongroup=-1
for i in $SELECTED_LSR ; do
eval tmp=${i}group
if [ "X$iscommongroup" = "X-1" ] ; then
iscommongroup=$tmp
else
if [ ! $tmp = $iscommongroup ] ; then
iscommongroup=""
fi
fi
done
Now think over, what will happen here. Before that
"if [ "X$iscommongroup" = "X-1" ]"
iscommongroup is set to -1. Hence we have to assume the test will be
successful every time. $SELECTED_LSR contains a list of ls-R files,
in this case "cache". ${i} has the value "cache" upon first run (see
above). The value of tmp is a combination of the value of i and
"group".
[EMAIL PROTECTED] ~ $ i=a
[EMAIL PROTECTED] ~ $ eval tmp=${i}group
[EMAIL PROTECTED] ~ $ echo $tmp
agroup
. After all that the value of iscommongroup is "cachegroup".
db_set tex-common/groupname "$iscommongroup" || true
if [ -n $iscommongroup ] ; then
#
# here we could be more intelligent and check wether the choosen group
# actually exist, and if not, reask again!
#
db_input low tex-common/groupname || true
db_go
fi
fi
#
# we do not care for user permissions in this setting!
#
, which is fed to debconf finally. Maybe I'm completely wrong, but
this code seems very broken to me.
