I don't see any systemd way to do that. I added a variant that only runs the sleep command if the uptime is sufficiently low. It's more a dirty hack, but this kind of delay is sort of a hack anyway. (more) |

A: Journalctl - how to restrict search to only certain boot IDs? Not directly, no. The argument `-b` only accepts a single id and using it multiple times only results in the last one being used. You can however loop easily over the file and get the output of all consecutive `journalctl -b` runs in a single less: ```shell while read BOOTID; do journalctl -b ... (more) |

A: How to delay systemd unit at boot/login? You can use ExecStartPre= to delay the execution of the systemd unit.

A: Can you reuse your home directory while distro hopping? Permission wise you generally shouldn't have problems. Ownership in Linux/Unix uses numerical IDs, and on every major distribution the UIDs for regular users start at 1000, meaning the first user that is created during installation uses the 1000. Having a corresponding group with the same name is als... (more) |

A: Dual booting without rebooting I don't see any way to implement this. XenDesktop would have been the closest thing I can think of, but it's been discontinued years ago, and it involved VMs, which you don't want.

A: Auto-enable FN-toggling for the first N FN keys I don't think you can. AFAIK the fn key behaviour is implemented in hardware, the OS is not aware if a key has been pressed with or without fn key.
