Package: fai-setup-storage
Version: 5.8.4
Severity: wishlist
File: /usr/sbin/setup-storage
Tags: upstream
The setup-storage(8) command has the following grammar for tmpfs
blocks:
volume ::= tmpfs <mountpoint> <tmpfs_size> <mount_options>
tmpfs_size ::= <sizespec>
sizespec ::= RAM:[[:digit:]]+%|[[:digit:]]+[kKMGTP%iB]*
This forces a line that looks like the examples in the manpage:
tmpfs /tmp RAM:20% defaults
tmpfs /scratch 3GiB defaults
... which is great if you want to control that. But in our
configuration, we're happy to delegate the decision of how big a tmpfs
should be to the kernel, which has its own defaults (50% of RAM at the
time of writing, I believe).
It seems there's no way to do that delegation in setup-storage(8)
right now: if I use `-` as a <sizespec>, I get the following error:
# setup-storage -f "disk-config/gnt-fsn" -X
Starting setup-storage 2.2
Using config file: disk-config/gnt-fsn
ERROR (line 15): invalid tmpfs size near " - defaults disk_config
nvme0n1 disklabel:gpt-bios gpt_bios_part:1 bootable:2
[...]
ERROR (line 15): Invalid volume: Was expecting tmpfs size but found "-
defaults" instead
ERROR (line 15): Invalid line: Was expecting '\n' but found "tmpfs
/tmp -
defaults" instead
Syntax error
(I'll also note the duplicate errors, with the first strangely
containing the entire configuration after the tmpfs keyword, stripped
here for brievety.)
It seems to me "-" should be allowed here, like this:
disk_config tmpfs
tmpfs /tmp - defaults
It's allowed in fstab and just worked fine in our previous
configuration.
Thanks!
