VACFS(4)
π VACFS(4) β like, the vacfs manual page, bestie
okay so real talk: this is vacfs(4) from the Kernel Interfaces Manual, and it's genuinely one of those pages you read once and suddenly everything makes sense. stay with me π
β¨ NAME β¨
vacfs β a Venti-based file system. that's it, that's the vibe. π¦
πΈ SYNOPSIS πΈ
vacfs [ -dip ] [ -h host ] [ -m mtpt ] [ -s srvname ] [ -M mem ] vacfile
π DESCRIPTION π
So vacfs takes the file system that vac(1) created and interprets it so it can be mounted into a Plan 9 file hierarchy. iconic behavior honestly. π₯
The data for the file system lives on a Venti server, and the root fingerprint is specified in vacfile. yes bestie, that's where it all comes from β¨
Now the part where I have to be honest with you: vacfs is currently rather limited. like, lowkey held together with hope:
- access is read-only
- clients are not authenticated
- groups are assumed to contain a single member with the same name
These restrictions should eventually be removed. until then we simply vibe with them π
π OPTIONS π
okay here's the whole lineup, no skipping, we're not doing that here π«Ά
-dβ print debugging information to standard error. messy but informative, yk? π-hhost β the network address of the Venti server. the default is taken from the environment variableventi. if that variable does not exist, then the default is the metaname$venti. yes, that's the whole rule, no cap β-iβ use file descriptors0and1as the 9P communication channel rather than create a pipe. direct line, main character energy π-mmtpt β the location to mount the file system. the default is not to mount. literally the default is "don't" π-pβ disables permission checking. yes queen, ignore the rules π-sβ the name of the 9P service to post. the default isvacfs.name, where name is vacfile without any directory name or extension. cute little derivation, slay π-Mmem β the amount of memory, in bytes, allocated to the block cache. the default is16M. budget queen π

ngl bestie, re-read the DESCRIPTION before you go mounting anything β read-only, no client authentication, single-member groups. it's giving "early days" and we respect it π
and that's the whole page, mwah π this was VACFS(4) from the Kernel Interfaces Manual, section 4 β go forth and mount responsibly, bestie πΈπ
