From b9f111b93f9f442f00266f338b14f25ca8685352 Mon Sep 17 00:00:00 2001 From: Zbigniew Jędrzejewski-Szmek Date: Sun, 11 Jan 2015 00:04:00 -0500 Subject: Support negated fstab options We would ignore options like "fail" and "auto", and for any option which takes a value the first assignment would win. Repeated and options equivalent to the default are rarely used, but they have been documented forever, and people might use them. Especially on the kernel command line it is easier to append a repeated or negated option at the end. --- src/fstab-generator/fstab-generator.c | 21 +++++++++------------ 1 file changed, 9 insertions(+), 12 deletions(-) (limited to 'src/fstab-generator/fstab-generator.c') diff --git a/src/fstab-generator/fstab-generator.c b/src/fstab-generator/fstab-generator.c index 64eed49523..bc4c1556ca 100644 --- a/src/fstab-generator/fstab-generator.c +++ b/src/fstab-generator/fstab-generator.c @@ -135,17 +135,15 @@ static int add_swap( static bool mount_is_network(struct mntent *me) { assert(me); - return - hasmntopt(me, "_netdev") || - fstype_is_network(me->mnt_type); + return fstab_test_option(me->mnt_opts, "_netdev\0") || + fstype_is_network(me->mnt_type); } static bool mount_in_initrd(struct mntent *me) { assert(me); - return - hasmntopt(me, "x-initrd.mount") || - streq(me->mnt_dir, "/usr"); + return fstab_test_option(me->mnt_opts, "x-initrd.mount\0") || + streq(me->mnt_dir, "/usr"); } static int add_mount( @@ -344,8 +342,8 @@ static int parse_fstab(bool initrd) { if (is_path(where)) path_kill_slashes(where); - noauto = !!hasmntopt(me, "noauto"); - nofail = !!hasmntopt(me, "nofail"); + noauto = fstab_test_yes_no_option(me->mnt_opts, "noauto\0" "auto\0"); + nofail = fstab_test_yes_no_option(me->mnt_opts, "nofail\0" "fail\0"); log_debug("Found entry what=%s where=%s type=%s nofail=%s noauto=%s", what, where, me->mnt_type, yes_no(noauto), yes_no(nofail)); @@ -356,10 +354,9 @@ static int parse_fstab(bool initrd) { bool automount; const char *post; - automount = - hasmntopt(me, "comment=systemd.automount") || - hasmntopt(me, "x-systemd.automount"); - + automount = fstab_test_option(me->mnt_opts, + "comment=systemd.automount\0" + "x-systemd.automount\0"); if (initrd) post = SPECIAL_INITRD_FS_TARGET; else if (mount_in_initrd(me)) -- cgit v1.2.3-54-g00ecf
