[Libguestfs] [PATCH] customize: firstboot: make sure to run Linux scripts only once

If a script does not finish, hangs, etc, it would be executed again at the next boot, since the injected firstboot.sh helper removes it only after it finished. Since firstboot.sh only runs executable files, then remove the executable attributes before running it, so it will not run again. Also, remove any file found in the scripts subdirectory, be it just run or run in a previous boot. This fixes RHBZ#1159651. --- customize/firstboot.ml | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-) diff --git a/customize/firstboot.ml b/customize/firstboot.ml index 67b9479..5f68a2e 100644 --- a/customize/firstboot.ml +++ b/customize/firstboot.ml @@ -57,10 +57,13 @@ then for f in $d/* ; do if test -x \"$f\" then + # remove +x from the script being executed, so it is not + # executed again at the next boot + chmod -x $f echo '=== Running' $f '===' 2>&1 | tee $logfile - $f 2>&1 | tee $logfile - rm -f $f + sh $f 2>&1 | tee $logfile fi + rm -f $f done fi " firstboot_dir -- 1.9.3
