58 | is an early-boot service that applies mount options | |
59 | listed in | |
60 | <citerefentry><refentrytitle>fstab</refentrytitle><manvolnum>5</manvolnum></citerefentry> | |
b4efdf97 | 61 | to the root file system, the <filename>/usr</filename> |
236bc757 LP |
62 | file system and the kernel API file systems. This is |
63 | required so that the mount options of these file | |
64 | systems -- which are pre-mounted by the kernel, the | |
65 | initial RAM disk, container environments or system | |
66 | manager code -- are updated to those listed in | |
67 | <filename>/etc/fstab</filename>. This service ignores | |
68 | normal file systems and only changes the root file | |
69 | system (i.e. <filename>/</filename>), | |
b4efdf97 LP |
70 | <filename>/usr</filename> and the virtual kernel API |
71 | file systems such as <filename>/proc</filename>, | |
72 | <filename>/sys</filename> or | |
845c5324 | 73 | <filename>/dev</filename>. This service executes no |
b4efdf97 | 74 | operation if <filename>/etc/fstab</filename> does not |
236bc757 LP |
75 | exist or lists no entries for the mentioned file |
76 | systems.</para> | |
