The prospect of changing my OS, applications, and practices due to such an ostensibly small issue is frightening. Note that we are not discussing 'I don't like change' but rather 'this unintentional change is incompatible with my physical disability.' Thus this is not a case of every change breaks someone's workflow."
My situation is as follows: all living expenses except food, luxuries and entertainment is covered by the wage of my girlfriend. That would leave me in a situation where we would be financially alright, but not well off, if I were to earn significantly less than I do now. I am convinced that I would be able to make it in system administration, however, that is not my passion. I am at an age where children are not a concern, and risks seem to be, at first sight, easier to take. I would like to hear the opinion and experience of fellow readers who might have been in a similar situation."
In related news, the Debian Installer team announced the first alpha of debian-installer for Jessie. Just the installer, not the distro as a whole (Jessie will be frozen in November). XFCE remains the default desktop, ia64 was kicked out of the archive, and a few new ARM variants are supported.
Several options are available for trying musl. Compiler toolchains are available from the musl-cross project, and several new musl-based Linux distributions are already available (Sabotage and Snowflake, among others). Some well-established distributions including OpenWRT and Gentoo are in the process of adding musl-based variants, and others (Aboriginal, Alpine, Bedrock, Dragora) are adopting musl as their default libc." The What's New file contains release notes (you have to scroll to the bottom). There's also a handy chart comparing muscl to other libc implementations: it looks like musl is a better bet than dietlibc and uclibc for embedded use.
