+### Building on ARM
+
+As of 2021-10-13, very little testing of Maneage has been done on arm64
+(tested in [aarch64](https://en.wikipedia.org/wiki/AArch64)). However,
+_some_ testing has been done on [the
+PinePhone](https://en.wikipedia.org/wiki/PinePhone), running
+[Debian/Mobian](https://wiki.mobian-project.org/doku.php?id=pinephone). In
+principle default Maneage branch (not all high-level software have been
+tested) should run fully (configure + make) from the raw source to the
+final verified pdf. Some issues that you might need to be aware of are
+listed below.
+
+#### Older packages
+
+In old packages that may be still needed and that have an old
+`config.guess` file (e.g. from 2002, such as fftw2-2.1.5-4.2, that are not
+in the base Maneage branch) may crash during the build. A workaround is to
+provide an updated (e.g. 2018) 'config.guess' file (automake --add-missing
+--force-missing --copy) in 'reproduce/software/patches/' and copy it over
+the old file during the build of the package.
+
+#### An un-killable running job
+
+Vampires may be a problem on the pinephone/aarch64. A "vampire" is defined
+here as a job that is in the "R" (running) state, using nearly 95-100% of a
+cpu, for an extremely long time (hours), without producing any output to
+its log file, and is immune to being killed by the user or root with 'kill
+-9'. A reboot and relaunch of the './project configure --existing-conf'
+command is the only solution currently known (as of 2021-10-13) for
+vampires. These are known to have occurred with linux-image-5.13-sunxi64.
+
+
+#### RAM/swap space
+
+Adding atleast 3 Gb of swap space (man swapon, man mkswap, man dd) on the
+eMMC may help to reduce the chance of having errors due to the lack of RAM.
+
+
+#### Time scale
+
+On the PinePhone v1.2b, apart from the time wasted by vampires, expect
+roughly 24 hours' wall time in total for the full 'configure' phase. The
+default 'maneage' example calculations, diagrams and pdf production are
+light and should be very fast.
