Fix slow boot after deleting Swap partition
/etc/fstab. You need to comment out the lines that mount swap partitions. Ideally you should do this before deleing the swap partition
/etc/initramfs-tools/conf.d/resume(with sudo) and comment out the swap partition
/etc/crypttabif you had an encrypted swap partition
/etc/default/grubif you had hibernation enabled for Ubuntu
- You should update the
/etc/fstabfirst, comment out the swap entries, and then delete the swap partition.
/etc/fstab afterwards didn’t really fix the slow boot issue for me.
Upon installing a virtualization package with
apt i came across this warning:
W: initramfs-tools configuration sets RESUME=UUID=2854a8db-6494-41d0-9cff-974714bb0b00 W: but no matching swap device is available.
The initramfs is an cpio archive. At boot time, the kernel unpacks that archive into ram, mounts and uses it as initial root file system. From there on the mounting of the real root file system occurs in user space.
resume The resume hook tries to autodetect the resume partition and uses the first swap partition as valid guess. It is possible to set the RESUME variable in /etc/initramfs-tools/conf.d/resume. The boot variable noresume overrides it.
I had originally created the Swap partition (a partition and no a swapfile), because a swap partition is required to be able to hibernate an Ubuntu system..
sudo nano /etc/initramfs-tools/conf.d/resume
Additionally, you can also try re-configuring the
initramfs-tools, but i didn’t need to do so.
sudo dpkg-reconfgure initramfs-tools
You should also check your GRUB file for a
sudo nano /etc/default/grub
You can either updated or remove the
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=UUID=ad6fb579-9cdb-4b29-8977-f9aa9ee57e6f"
