I agree. The CI system also spends days bootstrapping the Rust compiler chain. Any user who tries to install IceCat during that time will have a terrible experience. I've been keeping "libgit2" updates in 'staging' for that reason, even though it is below the ~300 rebuild limit. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAEBCgAdFiEEu7At3yzq9qgNHeZDoqBt8qM6VPoFAl23cFoACgkQoqBt8qM6 VPq6QQf/UXPS16wYWbPNln8OB7x72YYxd0Qsop9xCLOdUIc/yP9iYwnD7+qm7OVQ 6CwFBGsLMnZdSy9+GUbA0cQ/aUVn+Hc5JqQl32cvD07qWm6XKiRVEwbibW3r/f8i gLoXIz+mB5d/vTSESqIhdVk3AAYu0OJCh9lo8nkwzeA3F4G/Sj0xE5QdKZmrJqYi ZMlh3czVcYDDHRDoHoHO4I7WAmmkrcVEJeaJyAMqw00xoPXkkk6251W+lRpunbWS vsC86/iJZZy7JDoT+W4QIzstH/ZC0Z+MmnCaiKnVMqAfoU6T9NrO2fVNIEsEuFhz ib4xe8zFTVW/tA2Fv9LVtKGWro4F5w== =CSNc -----END PGP SIGNATURE----- --=-=-=--
