filesystem has changed. If it has, all information about the
file is purged from the cache and new data is retrieved from
the back filesystem. The default value is 30 seconds.
aaaaccccrrrreeeeggggmmmmaaaaxxxx=_n
Specifies that cached attributes are held for no more than _n
seconds after file modification. After _n seconds, all file
information is purged from the cache. The default value is 30
seconds.
aaaaccccddddiiiirrrrmmmmiiiinnnn=_n
Specifies that cached attributes are held for at least _n
seconds after directory update. After _n seconds, CacheFS
checks to see if the directory modification time on the back
filesystem has changed. If it has, all information about the
directory is purged from the cache and new data is retrieved
from the back filesystem. The default value is 30 seconds.
aaaaccccddddiiiirrrrmmmmaaaaxxxx=_n
Specifies that cached attributes are held for no more than _n
seconds after directory update. After _n seconds, all directory
information is purged from the cache. The default value is 30
seconds.
aaaaccccttttiiiimmmmeeeeoooo=_n Sets aaaaccccrrrreeeeggggmmmmiiiinnnn, aaaaccccrrrreeeeggggmmmmaaaaxxxx, aaaaccccddddiiiirrrrmmmmiiiinnnn, and aaaaccccddddiiiirrrrmmmmaaaaxxxx to _n.
bbbbgggg This option causes _m_o_u_n_t to run in the background if the back
filesystem mount times out.
ddddiiiissssccccoooonnnnnnnneeeecccctttt
Causes the cache filesystem to operate in disconnected mode
when the back filesystem fails to respond. This causes read
accesses to files already cached to be fulfilled from the front
filesystem even when the back filesystem does not respond.

The filesystem types nnnnffffssss2222, nnnnffffssss3333, and nnnnffffssss3333pppprrrreeeeffff are accepted for
compatibility with earlier releases. nnnnffffssss2222 is equivalent to vvvveeeerrrrssss====2222. nnnnffffssss3333
is equivalent to vvvveeeerrrrssss====3333. nnnnffffssss3333pppprrrreeeeffff is equivalent to nnnnffffssss with no vvvveeeerrrrssss====
option.
Options used by the _m_o_u_n_t(1M) command on normal filesystems are ignored
when applied to the root filesystem, since the _f_s_t_a_b file cannot be read
before mounting the root filesystem. These options include rrrrwwww and rrrroooo
(the root filesystem cannot be mounted read-only), ggggrrrrppppiiiidddd, qqqquuuuoooottttaaaa and
