Or a selinux thing; "seclabel" seems to be SELinux's fault:
% git grep LABELSUPP_STR
security/selinux/hooks.c: {Opt_labelsupport, LABELSUPP_STR},
security/selinux/hooks.c: seq_puts(m, LABELSUPP_STR);
security/selinux/hooks.c: match_prefix(LABELSUPP_STR, sizeof(LABEL
security/selinux/include/security.h:#define LABELSUPP_STR "seclabel"
Personally, I find my life has been much happier since I gave up on
SELinux as being too complicated to be secure.
