Hi
after reconfigure
building
/gnu/store/qnskr1r67lp92bgy136hqvm7r96s3qrd-upgrade-shepherd-services.scm.drv...
guix system: warning: exception caught while executing 'start' on service
'swap-/dev/mapper/guix-swap':
In procedure swapon: "/dev/mapper/guix-swap": Invalid argument
guix system: warning: some services could not be upgraded
hint: To allow changes to all the system services to take effect, you will
need to reboot.
after 2 reboots also
$ cat /proc/swaps
27s
Filename Type Size Used Priority
$ swapon -s
$ sudo swapon -s
$ swapon --all --verbose
$ sudo swapon --all --verbose
$
I do not see swap is getting enabled.
Thanks
