21 Subject only got touched. That's all I *need* to do. :-)

23 My machines have lots of installations[1], so my master bootloaders only load
24 default kernels (via symlink vmlinuz-cur), installation kernel(s),
25 memtest(s), or chainload. I maintain these manually.
26
27 Bootloaders on my / partitions are chainloaded to for choosing among multiple
28 installed kernels per distro. Their menus are typically maintained
29 automatically by them rather than me.

36 I can't remember ever using a distro without an initrd before Gentoo, or
37 needing /dev/ram* to boot except for an installation kernel.

39 [1] e.g., this is from the Athlon I installed Gentoo to 50 months ago, and
40 since decided not to use any time soon to get a newer/current Gentoo. Among
41 my machines, it has a slightly lower than average installation count.
