[Bug 1560942] Re: Support swap

it is working via manual intervention after login like: https://forum.snapcraft.io/t/enabling-swap-on-ubuntu-core/5440 i.e. i implemented the OS side of it ... but we still do not have any "snap set system.swap=" option to steer it or set via a gadget configuration option in the yaml, this

setting the snappy task back to in-progress. i kept it open for the work on the configure hook which is not done yet. the ubuntu-core-config change and core_support interface work are just infrastructure. the actual final implementation still needs to happen in the hook script. ** Changed in:

actually, scratch that, i'll add a systemd service so the interface only needs write access to a config file and can use the existing implementation to en/disable services we already have in place. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed

[Bug 1560942] Re: Support swap

@jdstrand: any suggestion for a file location here ? (we need to add swap file creation support to the core-support interface, so fallocate and swapon execution should be supported plus a writable path for a swapfile) -- You received this bug notification because you are a member of Ubuntu

[Bug 1560942] Re: Support swap

@mark: so how about "snap set core system.swap=512" config: core: system: swap: 512 # size in MB|auto where "auto" would select a certain percentage of free diskspace (somewhere between 5 and 10%) if it is unset (the default to not scare SD card users away) there wont be swap. --

Re: [Bug 1560942] Re: Support swap

[Bug 1560942] Re: Support swap

i guess it will either become a kernel cmdline option (that you set in the gadget indeed) to trigger a creation script in the initrd (if you need swap you perhaps want it really early because your system is low on ram ... i.e. before you clutter memory with userspace processes) ...or actually via

Note that this was assigned to snapd as the mailing list discussion led me to believe this would be implemented via the gadget snap, which is something snapd would need to support no? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu.

adding ubuntu-core-config (though it might perhaps better suit in initramfs-tools-ubuntu-core). in any case creating a swapfile and managing swapon/off is an image feature, unlikely to be handled by snapd. ** Also affects: ubuntu-core-config (Ubuntu) Importance: Undecided Status: New
