❯ aa-exec -p sbuild -- perl -e 'my $d = "x" x 200; foreach (1..52) {
mkdir($d,0700) && chdir $d or die "level $_: $!\n" }'
level 41: File name too long
❯ rm -rf
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
❯ sudo vim /etc/apparmor.d/sbuild
# Updating profile...
❯ sudo apparmor_parser -r /etc/apparmor.d/sbuild
❯ aa-exec -p sbuild -- perl -e 'my $d = "x" x 200; foreach (1..52) {
