forked from DL-Mirrors/termux-docker
cf32710a93
Adds the file `/data/data/com.termux/files/home/.static-dns-hosts.txt` with empty content to bind to it externally with some user hosts. The script `update-static-dns` then uses the regular system wide static-dns-hosts.txt and the content of this file. The user can edit it inside the container, and/or bind it with an external file.
