I have openSUSE Leap 15.0 installed on my laptop, with both / and /home (separate partitions, both on SSDs) encrypted. On booting, grub2 asks for the passphrase to decrypt /, then takes about 10 seconds to offer an OS to load (there's only one). When Leap gets the passphrase to decrypt /home, it immediately proceeds with loading the operating system. Why does grub take so long? It's definitely the rate-limiting step in the whole process. I have tried reducing GRUB_TIMEOUT to 1, and yes, I did run 'grub2-mkconfig -o /boot/grub2/grub.cfg' afterwards. GRUB_DISTRIBUTOR= GRUB_DEFAULT=saved GRUB_HIDDEN_TIMEOUT=0 GRUB_HIDDEN_TIMEOUT_QUIET=true GRUB_TIMEOUT=1 GRUB_CMDLINE_LINUX_DEFAULT="resume=/dev/mapper/cr_sdb3 splash=silent quiet showopts" GRUB_CMDLINE_LINUX="" Is there anything else I can tweak to reduce the boot time? -- Bob
