Subject: autofs breaks nis auto.master when there is a tab in nsswitch

Package: autofs
Version: 4.1.3+4.1.4beta2-2
Severity: grave

The diff for etc/init.d/autofs includes:
 #
 # Check for all maps that are to be loaded
 #
 function getschemes()
 {
- if grep -q ^automount: /etc/nsswitch.conf; then
+ if grep -q '^automount:[ \t]' /etc/nsswitch.conf; then
         grep ^automount: /etc/nsswitch.conf | \
                 sed -e 's/^.*://' -e 's/\[.*\]/ /g'
     else
         echo files
     fi
 }

However, the new grep is broken:

| weasel@olga:~$ grep '^automount:[ \t]' /etc/nsswitch.conf
| weasel@olga:~$ grep '^automount:[ ]' /etc/nsswitch.conf
                                    ^^^^ < that's a tab
| automount: files nis

Hi,

#296238 (dupe of #296243) was fixed in the latest autofs upload to sid (which
should enter sarge shortly), but I wrote the wrong bug number in the
changelog (_again_), thus this manual e-mail. Thanks for the bug report. :-)

Bitten by this myself today. grep doesn't speak "\t" AFAICT from the
manpage (so it's not broken, just being misused). I changed it to:
  if grep -q '^automount:[[:blank:]]' /etc/nsswitch.conf; then
which works for me. (But maybe that character class isn't supported by
all greps? *shrug*).
